The 4GB boundary here is MAX_DMA32_ADDRESS I guess? We are only having this problem because of the two DMA zones on x86_64. I thought Andi was getting rid of the first one at 16MB. If he would do so then ZONE_DMA could be used instead of DMA32 and everything will be fine. For now you may want to put #ifdef CONFIG_ZONE_DMA32 around this code since it depends on DMA32. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
